Apostle Island Ice Caves time lapse - great video!

Duluth, MN (NNCNOW.com) --- If you are wondering why the Apostle Islands Ice Caves are now closed, take a look at this.
This is a still frame time lapse of the Ice Caves during ice out last year. Sure, the ice looks nice in these photos.
But here is the same location just 24 hours later... definitely a place you would not want to find yourself.
Even in the middle of January, Apostle Islands National Park Rangers say the ice conditions are never truly safe, and given the right wind and temps they could change rapidly.
Tourism leaders say the ice caves helped boost the region’s economy by $10 to $12 million.
If you did not get a chance to visit the rare site this year, feel free to start praying for another bitter cold winter for next year.
